Data Releases

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Benthic-macroinvertebrate and habitat data in Chester, Delaware, and Philadelphia Counties, Pennsylvania, 1998-2021 (ver. 2.0, September 2025) Benthic-macroinvertebrate and habitat data in Chester, Delaware, and Philadelphia Counties, Pennsylvania, 1998-2021 (ver. 2.0, September 2025)

The Stream Conditions of Chester County Biological Monitoring Network was established by the U.S. Geological Survey and the Chester County Water Resources Authority in 1969. Benthic-macroinvertebrate, habitat, and stream chemistry data were collected annually from 1998-2021 at 18 fixed location sites. Additionally, nine flexible location sites were selected and sampled annually from 1998...

Dataset of C1-C6 Dissolved Trace Hydrocarbon Measurements in the Western "Wet Gas" Part of the Marcellus Shale Oil and Gas Play in West Virginia, U.S.A. Collected Between June and August 2018 Dataset of C1-C6 Dissolved Trace Hydrocarbon Measurements in the Western "Wet Gas" Part of the Marcellus Shale Oil and Gas Play in West Virginia, U.S.A. Collected Between June and August 2018

This dataset contains measurements of dissolved hydrocarbons in from groundwater samples collected in the shale gas producing regions of West Virginia, USA, between June and August of 2018. The target analytes in this study were: methane (CH4), ethane (C2H6), ethene (C2H4), ethyne (C2H2), propane (C3H8), propene (C3H6), i-butane (C4H10), n-butane (C4H10), 1-butene (C4H8), propyne (C3H4)...

New Source Rock Data for the Niobrara and Sage Breaks intervals of the lower Cody Shale in the Wyoming part of the Bighorn Basin New Source Rock Data for the Niobrara and Sage Breaks intervals of the lower Cody Shale in the Wyoming part of the Bighorn Basin

In 2019 the U.S. Geological Survey (USGS) quantitively assessed the potential for undiscovered, technically recoverable continuous (unconventional) oil and gas resources in the Niobrara interval of the Cody Shale in the Bighorn Basin Province (Finn and others, 2019). Leading up to the assessment, in 2017, the USGS collected samples from the Niobrara and underlying Sage Breaks intervals...

Eastern oyster Dynamic Energy Budget model outputs under current (2014-2020) and projected (2041-2050) temperature and salinity conditions in Texas and Louisiana estuaries and along northern Gulf of Mexico coast Eastern oyster Dynamic Energy Budget model outputs under current (2014-2020) and projected (2041-2050) temperature and salinity conditions in Texas and Louisiana estuaries and along northern Gulf of Mexico coast

Compilation of all outputs from the modeling study presented in Lavaud et al. (2023; IP-156006). In this study a Dynamic Energy Budget (DEB) model for the eastern oyster, Crassostrea virginica, was run under different scenarios of current (2014–2020) and future (2041–2050) temperature and salinity conditions across six key Texas and Louisiana estuaries to derive an aquaculture index...

Code for: Small enzootic survival costs mask the potential for long-term population size suppression Code for: Small enzootic survival costs mask the potential for long-term population size suppression

This repository contains all of the scripts to reproduce the analyses, figures, and tables associated with the manuscript Glorioso et al. in review. The scripts are organized into folders, and the folders are numbered in the order in which they should be executed. Briefly, there are six folders that do the following: (1) format the data, (2) fit the model, (3) run the population...

Microbial community analyses of groundwater collected during an enhanced bioremediation experiment of trichlorethylene in a fractured rock aquifer, West Trenton, NJ (2008-2015) Microbial community analyses of groundwater collected during an enhanced bioremediation experiment of trichlorethylene in a fractured rock aquifer, West Trenton, NJ (2008-2015)

These datasets contain microbial community data from groundwater samples collected at an in situ bioremediation site located at the former Naval Air Warfare Center (NAWC), West Trenton, NJ. DNA was extracted from groundwater samples collected from monitoring wells at the NAWC study site from July 2008 through July 2015 and analyzed for microbial community structure. Sample collection...
